[Solved] No network access after waking from sleep with High Sierra

[titust1]

Hi everyone,
I recently updated from Sierra to High Sierra. I use the MTB Intel built-in ethernet adapter (no Wi-FI). Network works fine, but when it wakes up from sleep, the network adapter doesn't get an IP address from DHCP, even if I <Renew DHCP Lease> in Ethernet / Advanced. If I click Renew it self-assigs an IP in the 169. range. Obviously I do not have Internet with that.
If I reboot everything is OK again.
Anyone with the same problem, any ideas guys?
Thanks a lot

Not a solution but it may get you back online without rebooting :

In Terminal :

sudo ifconfig en0 down

Followed by :

sudo ifconfig en0 up

Which Ethernet kext are you using ?

I checked my notes from the initial Sierra installation and it seems I used IntelMausiEthernet 2.2.1d1 with Multibeast.
But I did not do anything special during the High Sierra update about Ethernet

Actually, I've tried to do what you told me, to bring down and up the interface, but it doesn't help. The problem seems to be the DHCP. The network interface cannot get and IP from the DHCP and instead it self-assigns one.

[SOLVED] OK guys, I reply to my own post with a solution. I hope it will help someone in the future with this kind of issue.
The problem was certainly replace to the kext I used for the Ethernet. Don't know what I used, maybe AppleIntelE1000 or a wrong version of the IntelMausi... But I fixed this by following this link:

Though I used MultiBeast to install. I just deleted all AppleIntelE1000.kext from my Mac, and the I used the IntelMausiethernet.kext v2.1.0 which is for my Intel I-219V. And bingo... it works even after sleep

Thanks for this information - I'm working on a build with a GA-Z270X-UD3 and this was driving me crazy.
I used the newest version (2.3) of the IntelMausiethernet.kext and the network connection works as it should after waking from sleep. I had used the AppleIntelE1000 at first, which would lose its connection after sleep.

This worked for me on my Gigabyte Z87-D3HP.

Thanks!

Thank you for this tip. toggling with en0 down/en0 up restores my Ethernet connection until I find a permanent solution. My old Thinkpad T61 running Sierra (perfectly except for this issue) has an Intel 82566MM which doesn't appear to be supported by IntelMausiethernet.kext, so I'm using AppleIntelE1000e.kext v3.3.6.

Thanks for this solution, this helped me with my GA-Z97X-UD5H motherboard. Installed IntelMausiEthernet v2.2.0 and removed AplleIntelE1000e.kext v3.3.6.

Does the IntelMausiEthernet work for the GA-Z87X-UD5H?
